Science and Technology Log 

Our day began on Station 170 with calm seas, clear skies and warm sunshine. We completed the last sampling tow late in the afternoon and began the final clean-up. All the equipment and gear was washed down and packed. We are now headed back to Lewes, Delaware where our voyage began.

It’s hard to believe 12 days have gone by already. It has been amazing journey and I have learned so much. The men and women whose work takes them to the seas are to be commended. It is hard work with long hours in all kinds of weather. But in all of science team and crew I sense the pride and the commitment each has for their work. I am going home with stories and images to share with my classroom, friends and family with a first-hand perspective. And I leave my crew with profound gratitude for all they have taught me.

Personal Log 

I spent some time last night talking with the youngest member of the ship’s crew, Mary Moore. Mary comes from four generations of commercial fishermen. She admitted that she decided early on she did not want to follow her parents’ footsteps .But after looking at other career choices she came full circle and does indeed work at sea. Mary earned a Hundred Ton License which allows her to drive vessels up to 100 tons. She went to school in Florida for Seaman Training where she learned Basic fire-fighting, First Aid/CPR, Survival at Sea, and Personal Responsibility. When I asked her what she liked most about her job or the sea she said, “Just being out at sea–it feels like home.” Watching the last rays of sunlight dancing on the smooth, rolling sea, I can understand what she means. In twelve days I found a personal sense of accomplishment and a love of the sea as well.

Science and Technology Log 

Today a video camera was attached to the dredge.  Using the camera they are able to see when the dredge is actually on the ground to determine the amount of bottom contact.  It is important to verify sensors like these anytime you work in science. The inclinometer records angle changes that we can interpret into a time on bottom which can be used to calculate a tow distance or bottom contact. This is compared to the tow distance calculated from the GPS recorded by FSCS.   Unfortunately, the inclinometer angle change is not abrupt enough to determine the start time, so the camera is used to determine the amount of time before we start recording tow distance with FSCS.

We have two days of sampling left and then we begin to clean and pack. The first dredge today brought up so many sand dollars that they had to shovel some away before they could even secure the dredge! By late afternoon we were back into starfish; in all the dredges the scallop count was comparatively small.

Personal Log 

Around 4PM the skies cleared and we had sunshine again! It was a welcome sight after days of fog, cloud cover, and cold. That, along with calmer seas, made for a great day. Sitting on deck in the warmth of the Sun watching the wave action, I reflect all the different moods of the sea I have seen. I also think about all the wondrous animals I have seen; and wonder about how much more life there is that we didn’t see.

We have completed 138 stations and are halfway through today’s shift. Our transit today will take us to the closest we’ve been to the coast. Having said that, we are still about 40 miles offshore. The weather today has been better than we expected. Seas are still choppy, and the air is very cool.

Captain Jimmy Warrington
Captain Jimmy Warrington

Working out on deck requires us to bundle up. The fog has lifted after cutting visibility down to 100 ft yesterday! The captain said that he had three different computers going at the same time to insure safe navigation. This led to a conversation about how technology has changed on ships. Captain Warrington said in the old days all they used were 2 radars, a stopwatch, and “dead reckoning” where they lay out a line of travel (their course) on paper. As you can see from my past conversations about the science night crewmembers, people come from all walks of life to work in NOAA’s Fisheries Service. I have not written about the science day crew because the other Teacher At Sea, Elise Olivieri is working with them. Check out her logs to see what’s happening on her shift! And what about the ship’s crew?

First Mate Chris Bogan
First Mate Chris Bogan

We have Vessel Master James Warrington (the Captain). He has been with the University of Delaware for 25 years, and a Captain for 18 years. He started out as an engineer and decided he would like it better on the bridge! He has to go through re-certification periodically to maintain his license. I asked him what his most interesting assignment of all time was and he said it was working at the Bermuda Biological Station. Chris Bogan has been a Vessel Master since 1983 and is the First Mate on this cruise. He told me that 90% of his family had been sea captains, on both sides of his family!

Cook Paul Gomez

One of the most important crewmembers on board is Paul Gomez, the cook! Paul is originally from Ecuador. His family lives in New York, but Paul, his wife and children live in Delaware. Paul has worked with the University of Delaware for 5 years and stays out at sea most of the year. He has been out at sea for 165 days already this year. Paul says he really enjoys his work because of all the people he meets.  You can ask anyone on this cruise and they will tell you that he is a fabulous chef! And he is always smiling.

We had a lot of smiles this evening. We are within satellite range that has brought our cell phones back to life, at least for awhile. We are just off the coast of Manhattan, so everyone got busy with a call home. We also got a glimpse of city lights off in the distance. As I was getting into my foul weather gear again tonight, I started thinking about how many times this has happened this week. We have averaged 9 stations per day on our shift and have been working for 9 days so far, which means that I have put on this gear 81 times. This may sound trivial to you, but it’s one of those little details that help you laugh as you near the end of another long 12 hour shift!

Our day begins with calmer seas and some sunshine, the fog lingers, draped softly over the sea. We are making good progress in the number of stations sampled. However, there is word that a storm may be approaching on Sunday. We expect to be closer to the coastline by then, so perhaps we won’t feel the full brunt of the weather system. Wave action will determine if the dredge is deployed or not.

By late afternoon through tonight the winds have picked up again. Waves are pounding the ship as we move between stations. We’ve had some interesting catches today, mostly sand dollars with few scallops. But this evening we pulled up a large boulder! Then we had a catch with no scallops at all. Another dredge brought up a Windowpane flounder also known as daylight. If you hold it up to the light, you can see right through it! Another interesting specimen is the black rectangular egg sac of a Skate. You can see the embryo of the fish inside when you hold it up to the light as well. You just never know what‘s going to come up in the net. Yesterday I was talking about the green slimy secretion from sand dollars. Today Shad was telling me about Horseshoe Crabs. Turns out they have blue blood, the result of using copper to oxidize their blood instead of oxygen like we do!

In the few minutes that we have between stations, it‘s not unusual to hear the crew talking about their families and loved ones. Anecdotes shared accentuate the human factor in this service. Especially late in the shift, it’s fun to exchange stories about home. I’m back in my cabin ready to call it a night. As I lay in my bunk I feel the ship fighting against the waves. A funny thought occurred to me: the cabins are below the water! We’ve been sleeping “in the sea”!

We’ve been at sea for seven days now and the daily sampling continues. Winds are not as strong as yesterday and we’re all glad. Skies are overcast and a thick fog surrounds us. Nothing out of the ordinary occurred today. By the time our shift ended we had completed 9 sampling stations. The majority of the dredges brought up were full of sand dollars. Lots of sand dollars mean slimy green secretions all over everything! Live sand dollars have a felt-like coating of fine spines. They shuffle through loose sand and feed on diatoms and microorganisms. Flounders and other bottom fishes feed on them. Their color is highly soluble and stains.

I’ll continue my conversations about my day shift crew. Larry Brady is a Biological Science Technician with the NOAA Fisheries Service. A former business manager with McGraw-Hill, he began volunteering with the Northeast Region Fisheries Services Sandy Hooks Lab in New Jersey. He found he really enjoyed what he did. One thing led to another and he has now been with the NOAA fisheries for 9 years. His responsibilities include maintaining the FSCS hardware and auditing data.

Dr. Shayla D. Williams is a research chemist at the Howard Marine Science Laboratory in Sandy Hook, New Jersey. She is researching fatty acid chemical tracers in two Northeast fisheries key resource species: Summer Flounders and Black Sea Bass. Fatty acids are a reflection of one’s diet.  As Dr. Williams says, “You are what you eat.” Gary Pearson is on his first survey cruise. Formerly with the Massachusetts Military Reservation, 102nd Fighter Wing division, he has been with the NOAA Fisheries Service maintenance department for three years. Gary works with just about every physical aspect of this survey, except for data entry.

As the night shift came on duty tonight, “Doc” A.J. told me that he had sandwiched his head between pillows to keep from rolling around and slept just fine through the tempestuous day. So, once I finally got to my bunk I thought about what he said. I only had one pillow, but I did have my life jacket. So, I tucked myself between the life jacket and the wall. He was right! I didn’t roll either and slept all through the night!

We are at station 90 as I write, or try to write.  A front has moved in and brought wind and wave action that has us rolling. As I sit in the wet lab, the wind data on the computer jumps from 20-24 KTs. I had to write this journal entry by hand first because it was too difficult to work on the computer! However work proceeds, we just need to secure anything that can fall or roll. So how do we get on “station”? Stations are a pre-determined number of sampling stratums identified by beginning and ending Latitudes and Longitudes. Stratum is defined by depth intervals. Sampling is done in the same stratums every year, but the actual stations may not be the same.

Last night I was out on deck and saw lights dancing in the middle of the darkness. I was told they were the lights from other vessels. I asked why there were fishermen here if this was a closed area. Turns out that some commercial fishermen have special access permits that allow them to fish in pass-by zones. They can only use these permits a certain number of times for a certain number of years. I also learned that they are monitored by a satellite system that can see who is there.

I have mentioned some members of my shift crew in my logs. I would like to talk a little more about who they are, what they do and why they are here, in my remaining logs. Chief Scientist Kevin has been with the Fisheries Service since 2002. He is responsible for the overall operations on the science side. He oversees the Watch Chiefs; is responsible for data auditing and cruise track planning; and maintains communication with Woods Hole Oceanographic Institute about the progress of the survey.

Vic Nordahl is a Fishery Biologist at NOAA’s Northeast Fisheries Science Center in Woods Hole and is part of the senior staff of the group. He mentors and supervises the fisheries survey team and is out at sea two times a year with the scallop survey. He also does a triennial Surf Clam and Quahog survey. He is currently working on calibrating a time series between the NOAA Ship Albatross and the Research Vessel Hugh R. Sharp. The Albatross has been retired after 36 years of service. Shad Mahlum, our Watch Chief, is a Sea Tech with NOAA Fisheries Service. Before joining NOAA a year ago, he served 7 years in the Coast Guard. After the Coast Guard, Shad attended school in Bozeman Montana where he studied Zoology and Fresh Water fisheries.

Before I had even opened my eyes, I felt the ship rolling. Winds from a front that moved in are churning up the seas which make simple things like showering a real challenge. I know that while we are towing the dredge the ship moves slower so I waited in bed until I felt us slow down. Then I jumped up and raced into the shower hoping I could make it through getting dressed before we picked up speed. I almost made it! During one of our last stations a HUGE wave crashed all the way across the stern. I was in the wet lab processing scallops when I heard and saw the action. Wish I had had my camera ready! I think we work harder during these wave events because it’s just so hard to do anything without straining those sea legs and arms to maintain your balance! Hope we have a calmer day tomorrow.

“Monkey Dung”
“Monkey Dung”

The seas have been favorable to us again and we begin work under sunshine skies. We are still sampling in the Elephant Trunk area.  At this writing we are approaching station #75. We have had a variety of different catches today; in fact most dredges are different. One might be full of starfish, another full of sand or mud and crabs, and others full of scallops – every one of them is different. The biggest dredge of the day brought up about 4000 scallops!

Starfish and crab are also sorted and counted at every third station. There are primarily 3 different types of starfish in this area. Researchers do a representative sampling to estimate what types are out here. So far the biggest starfish I have seen had arms about 24 cm long (Asterias vulgaris); the smallest about .5cm. (Asterias forbesi). Starfish are natural predators to scallops. I have noticed that when the catch has lots of starfish, the numbers of scallops goes down. I asked Vic Nordahl about this and he said that it may be possible that the number of starfish suggests the results of predation, or it could simply be that this area is not good for scallops. Crabs are counted to determine numbers and distribution. The majority of crabs in this area are from the Genus Cancer: Rock crabs (Cancer irroratus) and Jonah crabs (Cancer borealis).

Sulphur sponges, or Monkey Dung, also come up in the dredges. It‘s a yellow thick sponge with pores so small that there don’t appear to be any. It smells like sulphur and looks like monkey dung! Are sponges plant or animal?  There is still some question about whether a sponge is an individual or a colony of sponges. Sponges are the most primitive of multi-cellular animals, and lack organs or systems. What we see in the dredges is only a very small sampling of the variety and numbers of species that call the sea “home”. And every organism that comes up in the dredges validates the reason for conducting fishery surveys.

Personal Log 

The 12 hours of work we put in each day goes by fairly quickly. My shift crew members lighten up the long day with their sense of humors and laughter.  But make no mistake, they take their work very seriously. I am always asking questions (as usual) and they always respond patiently. I really feel like a contributing member of this team now, not just a visitor. The night was cold on deck, so I head to my cabin with a cup of hot tea at the end of my shift. Tomorrow is a new day!

Answer to the question: What’s the difference between a Deep Sea scallop and a Bay scallop? 

Unusual eggs—what kind are they?
Unusual eggs—what kind are they?

A deep sea scallop is orange or cream colored, is a larger scallop and has a larger meat (adductor muscle).  The shell is not as concave and lacks the ridges of the bay scallop shell. They are distributed in depths from 20 meters to 150 meters.  A Bay scallop is smaller in size and has a smaller meat in proportion to the shell size. The shell is ridged and usually mottled colored in shades of red, white, brown and tan.  They tend to be distributed in depths from right at shore to 20 meters.  They occupy different habitats.

Wynne readies the CTD.

As soon as our shift began today, the dredge was already on deck so we went straight to work. After several stations I noticed that the scallop and crab count was lower than yesterday. We are working in an area called Elephant Trunk. It is named this because the bathymetry of the sea floor makes it look like one. We have many stations in this Closed area, so we may see an increase in scallop numbers as the shift progresses.

Today I learned about “clappers”. Clappers are scallop shells that have no meat in them. They are sorted out from the rest and counted. I asked Vic Nordahl why they were important and he said that clappers give us an estimation of natural mortality or predation, so they need to keep count of how many are found.

Can you see the Red Hake tucked in the scallop shell?
Can you see the Red Hake tucked in the scallop shell?

Between dredges today, I spoke with Wynne Tucker. Wynne is an oceanographic tech from the University of Delaware and is in her third season on this research vessel. Wynne does a CTD cast every third station. A CTD measures conductivity, temperature, and depth. She takes samples in the water column at depths of 50-70M. Sensors on the CTD send information to a computer where the data is recorded. The CTD also records information about fluorescence, presence of particulates, and oxygen. The data gives us a visual of the water column which is then sent to NOAA (the National Oceanic and Atmospheric Administration) for analysis. When Wynne is not doing CTD casts, she is working at many different jobs Larry Brady and I processed some special samples this evening. We usually measure 5 scallops. Two of the samples had a larval or young Red Hake inside. It lives inside the scallop shell for protection from predators and is tucked on one side of it. This is not a symbiotic relationship, rather more commensalism. I continue to be amazed about the life systems in these waters!

Elise Olivieri (the teacher from New York) and I have made plans to photograph each other as we work. We work different 12 hour shifts so we do not see each other except during the shift change. And as we have both learned, there is not time for picture taking once the work begins! Unfortunately, our pictures will not be included in our journals at this time, but will be added upon our return!

My day ended with two incredible sights. First, as I carried the special samples up to the storage cage, I looked out from the portside at a totally dark scene. You could not make out sky or sea- it all blended into …black! I have never seen anything quite like that before. The second occurred on the starboard side just as I was ending my shift.  Glen Rountree (NOAA Fisheries Service volunteer) told me he had seen a strange red light in the sky and after looking through his binoculars realized it was the Moon. Elise and I grabbed our cameras and went out on deck. It was beautiful! One solitary red light in the middle of black! It was a good way to end the day.

The new day brings overcast skies and a very aggressive science agenda. When I walked out on deck at the beginning of my shift I noticed everyone was bundled up, and it didn’t take long to figure out why. I also noticed many baskets of scallops-everywhere! Yesterday we were working in an Open area where commercial fishing is allowed, and the number of scallops we brought up in the dredge was very small. We even had one catch with no scallops! Why is this?

Is it overfishing, predation, larval transport lack of success, or just not a good area for scallops?

Gear is always ready to "jump into"!
Gear is always ready to “jump into”!

Today we were working in a Closed area and the number of scallops I saw was amazing. As the day progressed we continued to get large numbers in the catch and a variety of sizes. This area is very productive, the result of being allowed time to reproduce and grow.  As we move northward now, I was told that the number of scallops will grow even more. As promised, the work today was intense. We moved quickly between stations which meant that we had to process the catch and cleanup before the other station. (Sampling is done at pre-determined sites called stations.) The science team has a limited number of days for this survey, so the pace will most likely stay the same. We are at station 55/560 this evening!

Personal Log 

I think I have settled into the routine of doing a scallop survey. The timing between dredges varies, but I can anticipate when I have to put on my gear and be ready to go. The gear I speak of includes rubber coveralls, life jacket, rubber boots and gloves. They are always “at the ready” next to the lab door, along with cameras! After my first station at the sorting table I fully understood why we have to wear these cumbersome outfits. When we are finished sorting we have sand, mud, and stuff all over us! When the work for each station is complete, we hose off everything including ourselves! The evenings get really cool out here, so I have a light jacket to wear under my gear. This morning when I retrieved it from the lab I couldn’t decide whether to wash it or burn it!

Sometimes when the stations are very close to each other I stay in my gear and sit on deck to work on my journals or, just sit. Gazing out to the sea, I can understand the sense of responsibility these researchers have for insuring the sustainability of the seas. The ability to hold some of these marine specimens right out of the ocean brings meaning to this work.

We began our shift today sampling in an area called Del Marva Closed Area, which is an area currently closed to scallop fishing. We conducted 8 dredge hauls last night in spite of the turbulent weather that pursued us. But today, we had calmer seas and beautiful blue skies.

The serious work of sorting and measuring the catch begins right after the dredge is brought up and secured. As it is coming up, someone on either side of the dredge uses a rake to shake the net which allows the catch to fall out. After the net is secured, readings are taken using from a sensor mounted to the dredge. The sensor is called an inclinometer; it measures the dredge angle during the 15minute tow.  This allows the scientists to calculate the amount of time the dredge is on the bottom. Then I hop on the table to hold a whiteboard with the pertinent station information written on it next to the catch which is photographed for documentation. Then the frenzy begins! I leave and someone else gets on the sorting table to rake the catch towards waiting sorters who have several buckets and baskets ready.

The sorting begins!
The sorting begins!

The catch is a mixture of scallops, crabs, fish, lots of starfish, assorted other specimens and sometimes sand. We are primarily sorting out sea scallops and fish, but have had some stations that require us to sort out crabs as well. We work quickly to separate the catch which is then taken into the wet lab for measurement. I have been working with Larry Brady from NOAA Fisheries, learning how to measure scallops using the FSCS system. The FSCS is the Fisheries Scientific Computer System which is a collection of integrated electronic devices used to gather and store station and biological data. FSCS uses touchscreen monitors, motion compensation scales and electronic measuring boards. I feed Larry the scallops one after the other as he measures them using a magnetic wand. This information is automatically recorded into the data base. Last night we had a large number of scallops to process. However, today we have seen less and less; in fact we had one catch with none! The fish are not as plentiful either although we have seen various different specimens.

Starfish are plentiful on this catch!
Starfish are plentiful on this catch!

There are also special scallop samples that need to be processed. First, the scallops are cleaned with wire brushes. Then they are weighed in their shells. After this is recorded, they are opened to remove the meat and gonads, which are weighed separately. This information provides us with the gender of the scallop and can approximate their age. I dry the shells and number them. Then I put them into a cloth sack, tag them with identifying information and put them into the deep freeze.

The fish are also weighed and their species is recorded. Sometimes specimens need to be counted (I counted small crabs today).  Once all the measurements are taken, everything is washed down! That includes the deck, the sorting table all the catch buckets, the FSCS measuring boards and the lab floors. We are then ready for the next dredge haul which follows approximately 20-30 minutes later. This pace continues throughout the shift, barring any mechanical or weather issues.

I am very impressed by the precision of the work that the science team does. As I waited for the dredge to unload a catch this evening I reflected on how everyone does their job quickly and efficiently. It’s something I never fully appreciated – that there are people out on the seas doing this very thing all the time! Already in one full day, they have taught me so much about how the fisheries system works, and they have expanded my knowledge of different marine organisms. Even as we sort quickly through the catch, they are always identifying specimens to me and answering my questions.

One of the most amazing sights for me has been the incredible number of starfish that each catch brings up! I have never seen so many, and I am learning about the different types. I am also learning how to shuck scallops for the galley for dinner. So far this has not been strength of mine, but I am determined to master this skill! By the way, our lunch today was scallop soup! The beautiful sunset today gave way to the almost-full moon shining on the seas. My shift is over for tonight, I’d best get some sleep.

Animals Seen Today 

Dolphins—made a quick but too brief appearance alongside the ship today. I caught a glimpse as they raced by. Polka dot Kuskeel; Baby Goosefish; Loligo Squid (pronounced Lollie go!) Snake Eel; and Clear Nose Skate.

The Research Vessel Hugh R. Sharp set sail this morning around 8AM from Lewes, DE.  There are 13 members of a science team including two teachers: Elise Olivieri and myself. There are 9 crew members as well, for a total of 22 people onboard. We met this morning for introductions and a briefing on the schedule of the day. Captain Jimmy Warrington gave safety instructions and a muster drill was held on the stern of the ship. With logistics covered, the team got to work preparing for a test tow of the scallop dredge. The dredge is 8ft wide and is made of a metal frame from which netting and a bag constructed of rings is attached aftward. It is lowered with a winch off the stern of the vessel and descends to depths that range from 10 meters to 150 meters. As the ship moves at a speed of 3.8 nautical miles per hour for 15 minutes, organism is being scraped off the seafloor. A test tow is conducted near the shore to make sure this important equipment is working properly. In the event that something needs work, we are close enough to go back for repairs

The focus of this NOAA Fisheries cruise is to survey the population of Placopecten magellanicus, the deep-sea scallop.  Chief scientist Kevin McIntosh (NOAA-Fisheries) leads the team of researchers for Leg 1 of this survey which will do representative sampling.  Victor Nordahl (NOAA Fisheries) is responsible for organizing the sampling survey. The NOAA Fisheries Service monitors the populations of sea scallops in the federal waters on the Eastern continental shelf of the U.S.  In 2007, scallops represented the most valuable commercial fishery, along with lobsters. It is critical to monitor their populations to avoid over-fishing of these waters. Fishing areas are either open or closed, meaning that fishing is either allowed or not. Closed areas allow time for repopulation of the area of the commercial species. Temperature and depth are important for scallops. The species we are studying are found in waters cooler than 20C (68F) along the North Atlantic continental shelf area between Newfoundland and North Carolina. In the 12day time period of Leg 1 of this survey, we will conduct about 15 sampling stations per day, working 24hrs a day. I am working the noon-midnight shift. Today being the first day, my team will work from 4pm-midnight.On Sunday we begin the 12 hr. shifts. Each crew has a Watch Chief responsible for making sure everything runs well with the survey on his watch. Our Watch Chief is Shad Mahlum (NOAA Fisheries).

Rough seas sure made it hard to get those sea legs going!

My bunk mate for this cruise is Elise Olivieri, a TAS from New York. We share a small room with bunks and on the first night we realized that without a ladder to use, she definitely had to take the top! (Elise has more height to her than I!) We experienced some rough seas this first day due to storms that were circling around. When night fell, we could see lightning in the distance. We were tossed around quite a bit during the late hours of our shift, bumping into walls, equipment and each other! Waves pounded over onto the deck where we worked and sprayed chilly waters over everything it could reach. Sure made it hard to get those sea legs going.

By the end of my shift I felt that I had a good understanding of my role on the survey team. I am working with a great group people who have been most patient with all my questions. They are teaching me a lot about scallops, marine life and the importance of their jobs. This is going to be a great experience!

Question of the Day 

What’s the difference between an East Coast Deep Sea Scallop and an East Coast Bay Scallop?
